In this question, the first information that we get is that Kayla spent half of her weekly allowance in clothes. On cleaning the oven Kayla gets $4. Finally Kayla is left with $12.
Let us assume that the weekly allowance of Kayla = x
Amount of allowance saved after buying clothes = x/2
Then we can go for the equation
x/2 + 4 = 12
x + (4 * 2) = 12 * 2
x + 8 = 24
x = 24 -8
= 16
So we can now see that the weekly allowance of Kayla is $16
The only way i can think of working out this question is this:
t = time p = phone calls
insert what we know:-
93 = p + 50
make P on its own:-
take away 50 from each side
43 = p
switch (you don’t HAVE to do this) :-
p = 43
So, shivani has to route a total of 43 phone calls to spend a total of 93 minutes on the phone.
Answer:
20°
Step-by-step explanation:
AB = 70°
BC= 90°
AC=x
ASP (angle sum property)
180°= 70°+90°+x
180°= 160°+x
x=180°-160°
x=20°
Step-by-step explanation:
We need only two points to the plotting a graph of a line.
for x = 0
for x = 4
